"Although we gained victory over Ospreys at the start of the season, we all know not to under estimate them. Ospreys are a dangerous side, who can and do compete at the highest level, we need to ensure we give them nothing to play with.
"At training this week we will work hard in certain areas of the pitch, the focus will be to put down our patterns of play, after that, on the day, it's just a matter of us holding onto the ball and making the best use of any chances we have. We must put them under pressure.
"It's vital for our Magners League campaign that we win our home games and build a solid platform from them."
Only six points separate Ulster from Ospreys, on an extremely tight and competitive Magners League table.
The starting 22 will be named on Thursday at 12noon.
